Two months ago, I had the chance to play on a 2019 Steinway D equipped with their new "Spirio | r" system. The piano itself plays and sounds very nice, but I did find some issues with the Spirio system, and I learned some important things about it after the fact that I felt I had to mention in this video as well.
Here is the link to the great fellow who let me come to his house to review this piano!
